High Precision Alignment Section at CERN and its activities on development of robust, low-cost, micrometric alignment systems



Wednesday, November 24, 2021 - 11:00 to 12:00


In the accelerator domain, high radiation levels, ultra-high vacuum, cryogenic temperatures of the measured components and high electro-magnetic noise push accelerator surveyors to look for more robust, safe and accurate solutions of alignment. In the framework of the High-Luminosity LHC project at CERN, a range of new and - nan cost-optimized solutions using Fourier analysis based Frequency Sweeping Interferometry (FSI) and capacitive technologies are under development. Moreover, the safe and easy alignment of components located in radioactive areas, requires easy, low-cost and fast adjustment for the components, causing needs of development of special mechanical systems.

This presentation will show the activities of High Precision Alignment Section at CERN and its efforts to develop such robust and low-cost, micrometric alignment systems.


Mateusz Sosin is a section leader of High Precision Alignment Section, which is a part of Geodetic Metrology Group of Beams Department at CERN. The Section provides 3D, micrometric alignment solutions for specific accelerator components and is involved in research & development works to improve alignment techniques for HL-LHC and future colliders. From the beginning of his career at CERN, Mateusz works as a mechatronic engineer, focusing on development of micrometric alignment systems for use in harsh accelerator environment.
